Astronomers define a local standard of rest in our section of the Galaxy by the average motion of all the stars in our neighborhood 4. (Note that in using everyday words, such as "local" and "neighborhood", we do a disservice to the mind-boggling distances involved.
The expansion of the universe is the increase of the distance between two distant parts of the universe with time. It is an intrinsic expansion whereby the scale of space itself changes.The universe does not expand "into" anything and does not require space to exist "outside" it. Technically, neither space nor objects in space move.
Here, F describes the force acting, m is the mass of the object, and a is its acceleration, the change in its motion. Like motion, force has both a value or "strength", and a direction in which it acts. We commonly think of "acceleration" as a speeding up, but in physics it can also include a slowing down ("deceleration") as well as a change in direction.
